How to add a member to two user groups?

How do I add a member to two different user groups?

I created a Not Safe For Work Forum and want those members to also be considered "Member".

This is not possible yet. At some point in the near future though!

All righty. I suppose that the permissions will just cover having the NSFW user group and switch those who want it from member to that one. I'll see how that goes. Thanks!

Hmm yes, it's a bit annoying. I'll put the two different groups a bit higher in priority.

Need to add sub-groups or even add another selection and name it ranks :) IPS has that..
